The research line "Superconductivity" aims to research and development of superconductivity applications in the electrical sector, with emphasis on superconducting current limiters, aiming at the transfer of knowledge and technology to the Eletrobras System, industry and the electric sector national authorities.
This is a line of multidisciplinary research, which links fundamentals of basic science to applied research, being one of the few in Brazil to develop studies on superconductivity applied to the electric sector.
For its implementation, it counts on the support of the "Superconductivity" laboratories; of "Electrical and Magnetic Properties"; of "Chemical Analysis"; X-Ray Diffraction "," Mechanical Properties "and LABDIG, located in the Fundão Unit, in addition to the" Alta Corrente "Laboratory, located in the Adrianópolis Unit.
The line of research "Superconductivity" includes the following sublines:
· "Short Circuit Current Limiter Research and Testing"
· "Modeling and Simulation of Superconducting Current Limiters"
· "Characterization of Materials and Superconductive Coils"
· "Prospecting of Superconducting Cables for the National Electric Sector"
Superconducting current limiters represent a promising solution to the increasing increase in short-circuit current levels. Such limiters are based on the rapid transition from the superconducting state to the normal state when a short circuit occurs.A underlines "Short Circuit Current Limiter Research and Testing" studies the behavior of these devices and the establishment of methodologies of superconducting current limiters.
The sub-line "Modeling and Simulation of Superconducting Current Limiters", allows the prediction of test results, as well as a greater understanding of the operation of the device. The main goal is to simulate the performance of current limiters in the power grid through case studies.
The "Characterization of Superconductive Materials and Coils" is dedicated to the characterization of superconductors of high critical temperature, investigating their properties and their behavior. It also involves the development and study of superconducting coils for electrical applications.
Currently, Cepel is supporting Eletrobras in a prospective study on the implementation in Brazil of superconducting cables for transmission. This study is conducted jointly with the Japan International Cooperation Agency (JICA).
They are partners of Cepel in the development of the line of research "Superconductivity":
· The Laboratory of Applications of Superconductors (LASUP), of the Electrical Engineering Program of COPPE / UFRJ;
· The Laboratory of Superconductivity Applied (SUPERLAB), of the Department of Electrical Engineering of the UFF;
· The Materials Engineering Department of PUC-Rio.
